Is the septum what makes the tunica so tough to stretch

My septum feels like an I-beam made of gristle. During A-stretches, it has to lay one way or the other, and almost makes a click when it does so. I would imagine it is going to be a toughie to stretch. I wonder if the ratio of toughness between the septum and the outer portion of the tunica sheath is what makes some people girth gainers and some people length gainers? Does the septum run full length and is there a way to specifically target it?

Swing,

You don’t need to specifically target it unless it is the thing that is the tightest. If you pull out, is the septum tight while the rest of the shaft below somewhat slack? If so then it is the limiting factor (for the angle you pulled at least). In my progress report there’s some information on targeting the septum, pretty advanced stuff though.

How do you target the septum? Just straight out hanging-stretching?
Does stretching-hanging ots hit the septum or no?

>How do you target the septum?

Do the pulling out test thing I posted about above. If the septum is the tightest thing then pulling at that angle will stretch it. If not you don’t need to stretch it right now.

I’m pretty sure the septum consists only of circumferential fibers. Thus, there are no longitudinal fibers that could strongly resist stretching.

However, the outer longitudinal layer of the tunica is its thickest between the 11 and 1 o’clock positions, in a region called the “dorsal thickening.” I believe this is the area that gives many people trouble.

Tunica

I read the site you provided and thank you.

I am not sure if I understand it though, does this mean since the tunica is the thickest at the 11-1oclock position, does that mean when is it pulled to that angle? ( Not sure what the whole clock angle means)

If that was true, to change the formation of the penis/tunica, we should put stress on it at the thickest of the angles, which is why over the should and stretching towards the naval is the way to go?

Ps-another thing not so much related but if you know and don’t mind answering— what is the deal with elastic or inelastic-plastic.etc deformation? Does this have to do with cementing gains from the tunica?

The Tiger:

The positions of the clock mentioned in those articles refer to the penis in cross-section. They have nothing to do with angle of stretch. The dorsal vein is approximately 12 o’clock. The urethra is approximately 6 o’clock. The tunica is thickest between 11 and 1 o’clock, meaning that it’s thickest in the region right around the dorsal vein, where the the two CCs join on top.

There are also significant thickenings just to the left and right of the CS on the ventral (bottom) of the penis, called the “paraurethral ridges.” These presumably provide added strength along the ventral side, which is needed because there are no (or nearly no) longitudinal fibers directly above the CS.

To some extent, the strength of the paraurethral ridge might tend to even out the axial strength of the penis along the top and bottom surfaces. Therefore, I’m not sure whether it’s always preferred to focus stretching exercises on the top surface. To the extent that the different surfaces can be isolated, I think a divide-and-conquer approach would be best.

It might help to use a fulcrum to isolate different parts of the tunica. Stretch in a downward arc to hit the dorsal thickening and in an upward arc to hit the paraurethral ridges. You might even try biasing your stretch to one side at a time to isolate the different sides of the dorsal thickening and the different ridges.

Your second question was about plastic versus elastic deformation. This concept is borrowed from materials science and describes stress and strain on a rod composed of a given material. If you pull on both ends of the rod, it deforms. At first, deformation is “elastic,” because it will spring back to its original length and shape. But if you pull harder, it will stretch to a point where it will no longer return to its original size when the force is removed. This is “plastic” deformation.

Not everyone agrees that penis growth occurs through plastic deformation. Many people think it’s more of a biological than physical process, in which cells and tissues proliferate in response to applied force.

Deformation is a different concept from the idea of cementing gains. Cementing means continuing to do your workouts so that your body comes be “regard” the new size of your penis as “normal,” and thus resists the tendency to restore your penis to its previous dimensions. Cementing is probably required regardless of the underlying mechanism that causes growth.

MM, in your research into penile anatomy, have you found any further reference to the different directional strength in the tunica material? I was wondering what % strength it would have in the weak direction as a fraction of its strong direction.

I’m wonder if it may have say 50% strength in the weak direction, which would perhaps make sense from a structural point of view.

Mbuc,

I have no idea. Are you thinking about your “hollow tube” idea? As far as that goes, I haven’t heard anything that says the penis grows more easily in girth than in length. I think this will vary a lot from one guy to the next.

I was just musing about the physical property of the tunica material. I may be wrong but I was assuming that the inner and outer tunica material is the same except that their strong directions ran at 90’ to each other.

Obviously the different tunica layers must have some strength in their weak direction. I was just wondering how much.

A minor point, but I learned that viscoelastic means something slightly different. I would change your response to:
At first, deformation is “elastic,” because it will spring back to its original length and shape. But if you pull for an extended time, it will stretch to a point where it will no longer return to its original size when the force is removed. This is “plastic” deformation.

Silly Putty is the quintessential viscoelastic material. If you make a ball and throw it at the ground it will bounce back (elastic behavior). However if you put the ball on a table and wait it will eventually form a puddle. In the bouncing situation the forces are much stronger but the behavior is elastic. The time scale of the force is the distinguishing characteristic.

The tunica is literally stronger than steel as a matter of fact.

Mbuc,

Is the wikipedia the only reference you have found to the inner / outer tunica and different strength directions?

Yes, although I followed some of the links in it as well. I’m just too lazy to spend the time searching.

The ratio of the tensile strengths, in different directions, of a single layer of tunica was something I hoped someone might know off hand. :)

Great response Modestoman! I will fulcrum that I-beam into submission. Has anyone ever used the middle bar of a man’s bike as the fulcrum point for hanging SD?
